5.. Olivia made a 6 × 6 target on a 10 × 10 dartboard. She said that the probability of a dart landing in her target area would be twice as great as the probability that a dart will land in Liam's target area. Do you agree?
Yes; the dartboard is identical to Liam's but scaled up by a factor of two 

No; Olivia’s target area will be 4 times Liam’s target area, so the hit probability will be 4 times as great 

Yes; the area of the target is twice as big, so the probability of a hit is twice as much 

No; Olivia's reasoning is not taking into account the diminished nontarget area
